I had dyed dark blonde hair and I used a color corrector to remove it and then dyed it really blonde. The color was fine except there were tons of dark spots all over. So the next day I did the corrector again. Then dyed it and it is MUCH MUCH better but there still are a few darker spots, I can cover them up if I part it a different way but the next time I dye it I don't know if the new dye will cover it.. cause it didn't last time. It just looks uneven, no one can tell unless they are searching my hair for spots but STILL!What should I do?

I've answered your question on another thread. You should have followed my advice and you wouldn't be in this situation. You're ruining your hair every time you pour a box color over it. If you want your hair color to look even, you will need to go to the salon for color correction.
